The Holy Sith Empire, also called Darth Kalast's Sith Empire, or simply Sith Empire, was one of the first Sith Empires in galactic history, founded in 17,576 BBY by Darth Kalast. Hiding in the unexplored fringes of the Outer Rim Territories, Kalast and his small band of followers, what was originally a private fleet that he built up on Korriban, hid on a volcanic planet called Shola. From there, they expanded over the years and eventually conquered over a hundred civilized planets throughout the region. The Holy Sith Empire was formed by Kalast after the conquering, with him as the Holy Sith Emperor.
